LONG-TERM OUTCOMES OF EARLY CHILDHOOD SCIENCE EDUCATION: INSIGHTS FROM A CROSS-NATIONAL COMPARATIVE CASE STUDY ON CONCEPTUAL UNDERSTANDING OF SCIENCE

The purpose of this research was to explore the long-term outcomes of either participating or not participating in early childhood science education on grade 6 students?? conceptual understanding of science. The research is situated in a conceptual framework that evokes Piagetian developmental levels as both potential curriculum constraints and potential models of efficacy. The research design was a multiple case study of grade 6 children from 3 schools in China (n?=?140) who started formal science education in the third grade and grade 6 children from 3 matched schools in Australia (n?=?105) who started learning science in kindergarten. The students?? understanding was assessed by a science quiz and an in-depth interview. The data showed that participating children from the high socioeconomic schools in China and Australia had similar understandings of science. Divergence between the medium and low socioeconomic schools, however, indicated that the grounding in early childhood science education in Australia may have placed these children at an advantage. Alternative explanations for the divergence, including the nature of classroom instruction in the two countries, are discussed.     

Infants' attention to patterned stimuli: developmental change from 3 to 12 months of age

To examine the development of look duration as a function of age and stimulus type, 14- to 52-week-old infants were shown static and dynamic versions of faces, Sesame Street material, and achromatic patterns for 20 s of accumulated looking. Heart rate was recorded during looking and parsed into stimulus orienting, sustained attention, and attention termination phases. Infants' peak look durations indicated that prior to 26 weeks there was a linear decrease with age for all stimuli. Older infants' look durations continued to decline for patterns but increased for Sesame Street and faces. Measures of heart rate change during sustained attention and the proportion of time spent in each phase of attention confirmed infants' greater engagement with the more complex stimuli.     

Dialect variation,dialect-shifting,and reading comprehension in second grade

The purpose of this study was to examine second graders’ (n = 680) changing spoken nonmainstream American English (NMAE) use in relation to their oral language and reading comprehension achievement. Fall NMAE production was negatively associated with fall achievement scores. NMAE production generally decreased from fall to spring. Students who qualified for the US Free and Reduced Lunch program (FARL) and who had stronger language skills were more likely to decrease their NMAE use (i.e., dialect shifting) than their peers who did not qualify for FARL or their peers with weaker language skills. Dialect shifting for a sub-sample of 102 students who used substantial amounts of NMAE at the beginning of the school year was predicted by school context, controlling for reading and language skills—in general, students who attended more affluent schools dialect shifted to a greater extent than did their peers who attended higher poverty schools. Greater dialect shifting in this group predicted gains in reading comprehension from fall to spring.     

The use of career information delivery systems in the states

Conclusion The ever increasing demands on guidance and counseling programs has added new responsibilities to the tasks of the counselor specifically in the area of career development. Along with this increase in responsibility, the issue of accountability has been added. Career information delivery systems assist the counselor in meeting the need for accurate, relevant occupational and educational information that can be disseminated in a timely efficient manner. Therefore, CIDS should be a vital part of all comprehensive career guidance and counseling programs.Mary Elizabeth McCormac is an Occupational Information System Specialist, National Occupational Information Coordinating Committee, Washington, D.C.     

Neonatal Stress Reactivity: Predictions to Later Emotional Temperament

To investigate the relations among popular measures of neonatal stress and their link to subsequent temperament, 50 full-term newborns from a normal care nursery were examined responding to a heelstick blood draw. Baseline and heelstick measures of behavioral state, heart period, vagal tone, and salivary cortisol were obtained. Recovery measures of behavioral and cardiac activity were also analyzed. Mothers completed Rothbart's Infant Behavior Questionnaire when their infants reached 6 months of age. Baseline vagal tone predicted cortisol in response to the heelstick, suggesting that baseline vagal tone reflects the infants' ability to react to stressors. Greater reactivity to the heelstick (more crying, shorter heart periods, lower vagal tone, and higher cortisol) was associated with lower scores on "Distress-to-Limitations" temperament at 6 months. This finding was consistent with the expectation that the capacity to react strongly to an aversive stimulus would reflect better neurobehavioral organization in the newborn. Recovery measures of cardiac activity approximated and were correlated with baseline measures indicating the strong self-righting properties of the healthy newborn. Finally, vagal tone and salivary cortisol measures were not significantly related, suggesting the importance of assessing both systems in studies of the ontogeny of stress-temperament relations.     

Environmental print and word reading

The nature of the earliest stage of reading was examined by comparing two views about the importance of environmental print in children’s learning experiences. One theory holds that environmental print leads to the acquisition of reading through developing rudimentary representations of specific words and logos, while the second theory concerns assembled phonology and asserts that reading begins with knowing letters and their sounds. Supporters of this theory hold that knowledge of environmental print and logos is reading the environment and may not directly facilitate the acquisition of word reading. Two studies were conducted with non-reading preschool children in which environmental print knowledge was assessed and related to word recognition training. In the first session of each study children were presented with accurate representations of environmental print and logos such as ‘McDonalds’ and ‘Stop’ to find the ones they were able to identify and the ones they failed to identify. In the second session learning trials were conducted with those words from the logos that the children identified and also those that they failed to identify and with matching control words. Both studies found that the words from the known logos were more readily learned than the matching control words, but only in Study 1 were the known logo words learned more readily than the ones the children did not know. The results were discussed in terms of Gibson’s (1969) theory of perceptual learning, and supported the view that environment print and logo knowledge facilitated word reading.
